Abstract

This The Wireless Air Quality Monitoring System is designed to monitor environmental conditions in real time using IoT technology. The system detects harmful gases present in the air using gas sensors. It also measures temperature and humidity using appropriate sensors. An ESP8266 microcontroller is used to process the collected data efficiently. The system continuously compares gas levels with predefined safe limits. When the gas concentration exceeds the threshold, a buzzer is activated to alert users immediately. The processed data is transmitted wirelessly using Wi-Fi technology. Users can monitor real-time data through the Blynk IoT mobile application. The system is cost-effective, easy to install, and suitable for both indoor and outdoor environments. Overall, this project provides a reliable solution for improving safety and environmental monitoring.
